Army of Two Walkthrough & Strategy Guide

The first briefcase in Afghanistan (and the first briefcase you'll encounter in the entire game, at that) is near the first M-11 missile you encounter. You'll want to begin your approach to the briefcase by first clearing out all of the enemies in the vicinity of the gigantic Soviet-era missile, including the pesky machine-gunner that has you pinned down for most of the fight.

After the enemies are all cleared, head to the location of the stationary machinegun (the missile silo should be directly adjacent to you). Seek out a rocky ramp-like path that leads along the rockface. You'll come to a battered wooden bridge at the top of the ramp, where the briefcase full of valuable intelligence is resting.

Briefcase #2

Now, before you make your escape, there's another briefcase in your vicinity that you should grab for another quick $3,500. Simply head eastward from where you just killed the heavily-armed soldier. Seek out a secluded staircase heading upward.

From here, it's a no-brainer. Simply run up the stairs and grab the briefcase sitting there! That's another $3,500 in the bank.

Briefcase #3

Towards the end of your mission, you'll have to rescue a captured soldier named Brian Hicks. It's the only reason you were in Afghanistan in the first place (well, rescuing him and destroying some Soviet-era missiles and warheads), so knowing when you're in his vicinity shouldn't be too difficult to ascertain.

After climbing a flight of stairs, you'll have to do battle with a last pocket of enemy resistance adjacent to the jail cell. When you clear the enemies, you may be tempted to head left down some stairs and towards the cell itself. But before you do that, head down the corridor where the enemies were located next to the cell. You'll come to a dead end, but that dead end holds the briefcase you seek.
